To @ZZ whom t may Concern:

Be it known that l, LUCLENpBonHAUEn, a citizen of the United States of America, and a resident ot Chicago, county of Cook, and

State of Illinois, have invented certain new f a -d useful Improvementsin Beds, of which the following is a specification.

The main objects of this invention are to provide a convertible twin bed' device including a pair of relatively movabl'ebed frames capable of lateral adjustment Y to form a double-sized bed when occupying one position with respect to eachV other, and to form two single-size beds when occupying another position with respect to each other; to provide improvedtrack members for supporting said bed frames on a standard form of bedstead ;l to provide improved end members for slidably supporting saidbed frames on said trackmembers; to provide improved means on said trackmembers for retaining 'said bed frames in abutting relation; to provide an improved form of bracket on each end of said track members for retaining said bed frames in spaced relation; and to provide improved meansl for adjustably supporting said track members on said bedstead. y

An illustrative embodiment of this invention is shown in the accompanying drawings, in which- Figure l'is a plan of the improved bed structure as it appears when used as one being shown in dotted outline.

The improved form oit` bed shown in the drawings comprises a bedstead l, a pair of transversely disposed track members 2 adjnstably mounted thereon, and aA pair of individual bed trames 3 ande slidably supported on'said track members so as; to be adapted to'be laterallyyshitted toward and away from each other. 'Thebedstead L isof standard'form having side railsgorangle bars 5 and end rails 61 supported by the: pillars?. Y

The track members 2 are supported on the side rails 5, one at each end of-the bedetzead enddisposedi transversely thereto. Each of said track members is: or? a length substantiallyeqnal vto the distance between the side' Trails. of the. bedstead and is of inverted T- `shaped cross-section so as to provide, aweb Shaving a longitudinally extendingshoulder 9 on eachside thereof. VThe web Siscut away at the ends of the trackmembers so as. to form guideways 10, each of said guideways being of a length substantially equal plane. A horizontally disposed recessl is formed at Veach end of the track members 2 jfor engaging the horizontal legr of' each' of the angle bars 5. whereby the track members are ad] ust-ably supported on the bedstead.

InY mounting the device on abedstead having` wooden side. panels,'1tbecomes neces sary to bolt or otherwise secure angle' irons V,all being disposed substantially the same Y on the inner faces oi?` the side panels, as Y shown in Fig. 11. These angle irons may be o'short lengths, one secured at each end of the side panels. Y i A Y A reinforcing end bracket 16 isrig'idly secured to each end of the track members,

said bracket being preferably cast vtothe form shown in Fig. 10.V Each of the brackets 16 comprises a pair of fianges'l die. posed in substantially parallel spaced-relation and integrally ysecurecl together at their v10o Y 2 Las outer ends by a part 18 which serves as a stop to limit the outward movement of the bed frames. The brackets 16 are secured to the track members by rivets 19, said track members being formed and indented laterally at their ends so that the flanges 17 lie with their outer faces flush with the sides thereof, the flanges 9 and the outer parts'of web 8 bein fut away accordingly. Flanges 20 are foi .ied on the brackets 16 at right angles to the flanges 17 and engage the lower surface of the track member 2 so as to reinforce the ends thereof and prevent any splitting by the rivets 19 when the members 2 are made of wood. The upper edges of the flanges 17 are recessed as at 21, adj acent the part 18 and in alinenient with the grooves le so Vas to form continuations thereof. Shoulders 22 are formed on the sides of the lianges 17 to strengthen the bracket and also to forni continuations of the shoulders 9 of the track members. The depending parts 23 ofthe flanges 17 are spaced inwardly fronithe recesses 15 so as to allow for the cutting of different sizes of recesses, depending upon the distance between the angle bars 5;

Each of the bed frames 3 and t comprises a bed 'spring 211 supported on a spring frame 25, said springframe havinga depending Y end member 26 securedsto each end thereof.

The end members at the foot 'and head lof eachbed spring are also connected by a pair of rods 27 disposed longitudinally beneath said spring. 'Y

Each of the end'inembers 26 comprisesa channel-shaped Vmember 28 having a supporting bracket 29 integrally formed at each end thereof, said bracket 29 being detachably secured to the spring frame 25 by bolts 30. The lchannel-shaped members 28 are adapted to straddle the webs 8 of the track members and are slidable thereon, each of said members comprising a pair of depending flanges 31 disposed in parallel'spaced relation. A' pair of bearing projections, perferably in the form of kor including rollers 32 and 33, aresiipported in substantially the same horizontal plane between the flanges of each channel member'. The rollers are carried by pins supported on the flanges 31 and secured against displacement 'by Cotter pins 35. The rollers 32 are located adjacent the inner ends of the channel niembers and are slidable in the slots 11 and 12. The rollers 33 areA located at substantially tlie center of the longitudinal aXes of the bed frames and are slidable along the guideways 10. Y

When the bed frames 3 and 1 are in abutting relation, the rollers 32 are located at the inner ends of the slots 11 and 12, and the rollers 33 are seated in the grooves 13. When the bed frames are used as twin beds, the rollers 32 are located at the outer ends y said track me .ibenbearings frames and slidably engagingsaid of the slots 11 and 12, and the rollers 33 are seated in the grooves 14. When the rollers 83 seated in the grooves 13 or 141-, the bed frames are thereby secured against any latlWhen the device is in twin bed form, the

weight of each bed frame is evenly distributed or balanced over the angle bar upon wnich it rests, and so precludes the possibility of tilting when only one of the beds'is used. Moreover, the overhanging side 0f a section in this position projects so little relative to the width vand weight of the device as a whole, that there is no danger of tipping, even when one sits on the cuter edge.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numer-V ous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the followino claims.
